Sri Lanka’s Telecommunications Regulatory Commission, which had reportedly been monitoring social media for hate speech related to the violence, has temporarily blocked Facebook, Viber, WhatsApp, and Instagram in most parts of the country.

On Wednesday, Cabinet Spokesman Rajitha Senaratne said the government had asked internet service providers to block messaging apps after it was Facebook posts encouraging violence towards the country’s Muslim population were discovered.

Mano Ganesan, Minister of National Coexistence Dialogue and Official Languages, also confirmed the government’s social media ban on Twitter, saying the country had decided to curb “all communal hate speech posts via social media.”

Senaratne said in a press conference Wednesday that officials have been investigating who is fuelling calls for riots and that several parliamentary officials had been mentioned.

After a state of emergency was declared on Tuesday, curfews were instated in the central district of Kandy, a popular tourist destination that was the epicentre of Sunday clashes between the Buddhist Sinhalese majority and local Muslims, who make up about nine per cent of Sri Lanka’s population.
